I'm joining two pieces of tube together with a smaller diameter tube inside the two. I'm machining the joining tube out of something else, so I can choose how well it fits. I can't pin it, I can only glue it
I've bought 'super strong' metal epoxy for the purpose. So there are two questions:
1) Is epoxy going to be better than cyanoacrylate?
2) How tight should the fit be? Too tight and there'll be no glue left to bond, won't it? I've made a bit that slides in and out perfectly, should I make it more of a press fit?
It's only about 8mm diameter overall, so it's pretty small, and it needs to take a bit of torque.
